Answer:
-67p + 15
Step-by-step explanation:
Hello!
Expand the parenthesis and simplify by combining like terms.
<h3>Simplify</h3>
- 5(-4p-8p+3)-7p
- -20p - 40p + 15 - 7p
- -67p + 15
The simplified form is -67p + 15.
Given:
Consider the below figure attached with this equation.
To find:
Length of side ZX.
Solution:
From the figure it is clear that, WXY is a right angled triangle.
According the 30°-60°-90° theorem, the longer leg (opposite to 60° angle) of the right-angled triangle is 
times of shorter leg (opposite to 30° angle).
In the below figure, WY is longer leg and XY is shorter leg.
So, the length of XY is 8 units.
VWYZ is a rectangle, so
Now,
So, the length of ZX is 18 units.
Therefore, the correct option is C.

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x(x² + 4x - 5)
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x </em>[Function]: f(-2) = 3(-2)[(-2)² + 4(-2) - 5]
- [Brackets] Evaluate exponents: f(-2) = 3(-2)[4 + 4(-2) - 5]
- [Brackets] Multiply: f(-2) = 3(-2)[4 - 8 - 5]
- [Brackets] Subtract: f(-2) = 3(-2)[-4 - 5]
- [Brackets] Subtract: f(-2) = 3(-2)(-9)
- Multiply: f(-2) = -6(-9)
- Multiply: f(-2) = 54
X: 2/3.
Y: -1
Those are the values
